Dahlella
''Dahlella caldariensis'' is a species of leptostracan crustacean which lives on hydrothermal vents in the Pacific Ocean. ==Description== ''Dahlella'' may reach a length of from the base of the rostrum to the end of the abdomen. Much of the animal is covered by a large, hinged carapace. ''Dahlella'' can be distinguished from other animals in the same family by the presence of a row of denticles (small teeth) on the eyestalks, which it is believed are used to scrape surfaces for food. A similar character is found in ''Paranebalia'' (Paranebaliidae), but the form of the eyestalk is very different in the two taxa.〔
